DIVIDED AXLE FOR RAILROAD-CARS.

To all whom fit may concern:

Be it known that I, RICHARD VOSE, of the city, county, and lState of New York, have invented a new and Improved Compound Car-Axle; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specilication, Figure l being a longitudinal vertical section in a line passing through the center of my improved axle and t-he wheels combined therewith; Fig. 2, a. transverse section in the line y y of Fig. l, and Fig. 3, is a view of one of the tubular coupling segments detached from the` axle.

Similar letters indicate like parts in all the figures.

My invention consists in combining the cylindrical parts a, a, of the axle to each other without the use of screw-bolts or rivets, and in such a manner that the said parts cannot be separated from each other without removing the wheels from the axle. This I accomplish by means of recessed journals b, on the inner ends of each of the parts a, a, the recessed connecting segments c, c, and the embracing tube (Z, combined with each other substantially as represented in the accompanying drawings. The radiating flanges at the inner ends of the journals b, b, being received into the recesses e, in the connect-ing segments c, 0, will prevent the. parts a, a, of the axle, from being drawn apart so long as the said segments are kept closely united to the said ournals. The embracing tube d, will render it impossible for the connecting segments c, c, to get out of place, for the reason that the length of the tube is such that the segments c, c, cannot be uncovered, without-removing one of the wheels from the axle to enable said tube to be moved endwise a sutlicient distance to uncover the segments c, c.

The respective parts a, a, of my improved axle, will rotate independently of each other, whenever circumstances may render it necessary or desirablel that such should be the case.

Should it be deemed advisable to place any lubricating oil within the central portion of this axle, a small aperture be formed in the embracing tube CZ, opposite the connecting segments 0, c, which aperture may be closed by the screw plug f, or its equivalent.

I do not claim the use of an embracing tube for holding the inner ends of a divided axle, as that has been similarly used before,-but

lVhat I do claim and desire to secure by Letters Patent is- The connecting segments c, c, when com bined with the inner ends of a divided axle and the embracing tube (6L) substantially as herein set forth.

The above specication of my new and improved compound car-axle signed this 24th day of November 1855.
